FgivenA {iemisc} | R Documentation |
Future value given Annual value (Engineering Economics)
Description
Compute F given A
Usage
FgivenA(
A,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
FA(
A,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
Arguments
A |
numeric vector that contains the annual value(s) |
n |
numeric vector that contains the period value(s) |
i |
numeric vector that contains the interest rate(s) as a percent |
frequency |
character vector that contains the frequency used to obtain the number of periods [annual (1), semiannual (2), quarter (4), bimonth (6), month (12), daily (365)] |
Details
F is expressed as
F = A\left[\frac{\left(1 + i\right)^n - 1}{i}\right]
- F
the "future equivalent"
- A
the "uniform series amount (occurs at the end of each interest period)"
- i
the "effective interest rate per interest period"
- n
the "number of interest periods"
Value
FgivenA numeric vector that contains the future value(s) rounded to 2 decimal places
FA data.frame of both n (0 to n) and the resulting future values rounded to 2 decimal places
